胃结肠手术部位感染相关危险因素研究

目的探讨胃结肠手术部位感染(SSI)的危险因素,为SSI的预防控制措施提供依据。方法采用目标性监测的方法,研究胃结肠手术后SSI的发生,采用SPSS 10.0软件对其相关危险因素,如术前住院日、血糖、外周血血浆白蛋白、术前发热、手术持续时间、手术方式、ASA评分、内镜使用、失血量、术后引流管放置天数、入住ICU等25个变量进行单因素和多元logistic回归分析。结果 502例胃结肠手术后SSI发生率为6.17%,其中住院期间感染24例,感染率为77.4%,出院后随访感染7例,感染率为22.6%;多元logistic回归分析显示,血糖异常(P=0.002)、手术持续时间长(P=0.000)、内镜使用(P=0.032)是SSI发生的主要危险因素。结论胃结肠SSI是多因素综合作用引起的,开展目标性监测加强对临床干预可促使医疗质量持续改进,降低SSI发生率。
